The optical filter under development employing frustrated total internal reflection is a micromechanical device containing two silicon rectangular prisms. There is flat silicon plane among hypotenuse edges of the prisms. The silicon plane is a Fabry-Perot resonator, with clearances h_1 among the plate and prism edges being its mirrors. Theoretical resolution of the optical filter would be R ≈ 1,5·10~3 if h_1 = 50 μm and R ≈ 3·10~5 if h_1 = 100 μm with the thickness of the silicon plane being h = 65 μm; wavelength X = 100 μm; free spectral region AX/λ ≈ 0,3...0,4, transmission in the maximum of spectral characteristics 0,6 (provided input and output silicon prism legs bloom).
